Frozen Mice Packaging

I've received my very first online order of frozen mice. After the pack is opened and the first mouse removed, do you folks have any recommendations as to whether it's better to leave the rest of the mice in there, or put each one into its own baggie?

Honestly, I have never bought rodents, as I breed my own, but if I were to buy some I would take out what I needed and reseal the bag they came in leaving them together. If the bag cannot be resealed the I'd just put all of them in an appropriately sized resealable freezer bag and take out what I needed when I needed it. I see no reason for individual packaging.

when i get big orders of F/T i take them home and separate them into smaller portions (like from a 30count bag of pups ill separate them into 3 bags of 10) and a 25 bag of smalls ill separate into 3 bags as well. This way most of them stay in the freezer and dont get exposed to air a whole lot.

I vacuum seal all my rodents in bags for a monthly serving. So when a bag is opened that bag will be used for that months feedings. The rest are vacuum sealed and good for a year in freezer.

Thanks for the replies, folks. :)
